1 Anti-condensate heater data for unlighted rear sill. For lighted rear sill, double the values.
2 Model ON6UM only available for meat application with a thermopane-glass front or a curved plexiglass front.
3 BTUH/ft notes:
- Listed BTUH/ft indicate parallel operation. Conventional ratings may be approximated by multiplying listed rating by 1.11.
- Listed case BTUH/ft indicates unlighted shelves. For T8 lighted shelves and 3rd row lighting, add 80 BTUH per 4’ lighted shelf and 60 BTUH per 3’ lighted shelf to determine Total
Lighting BTUH Load, then divide the Total Lighting BTUH Load by the length of the case. For LED lighting, add 36 BTUH per 4’ lighted shelf and 27 BTUH per 3’ lighted shelf to
determine Total Lighting BTUH Load, then divide the Total Lighting BTUH Load by the length of the case.
- Standard fans increase refrigeration load by 96 BTUH/fan.
